SOFTWARE import into spacegass from REVIT

[Nicolas R.]

Hi all,

I am trying to import geometry from a revit model into spacegass considering the size of the structure. I have tried DXF format and IFC steps but both display sections as 3D - defining thickness and webs/flanges of steel beams/columns - I need an analitical stick model defined by 2 points to work in spacegass.

Can anyone assist me the right format importation to achieve this? Or explanatory comments. THanks in advance.

Regards,

NRR

As far as I know, Spacegass is quite responsive if you ask them a question. I would contact them and ask...

I'm not sure of most peoples workflow.

But normally there is sufficient difference between an architectural/detailed member model and a structural line model that converting between is normally not the best work flow approach.

Besides the sanity checking process of doing it by hand it very useful in my opinion.

(Maybe other people's experience are different but I generally haven't found the time benefits of detailed model to structural model advantageous.)

I have done it from an IFC before and not had that issue specifically - stuff came through as single lines
I did find it was nowhere near as helpful as you think though
Some issues I found:

1/ Timber joists didn't reach to beam centrelines due to timber packing causing offsets etc
You have to extend every member to connect to the supporting members

2/ It imports as individual section & material properties for every single element - it takes quite a while to fix stuff

3/ Revit loves to input subtly different (x,y,z) coordinates for things that, analytically, are on the same plane
This is more accurate to construction reality but is a pain in the ass for structural modelling - it takes a loong time to fix

4/ Things import without any fixity releases, so you better watch carefully to make sure you add them all in later

There were more challenges too but those were the biggest ones

In my case, I think it was worthwhile as my building had lots of angles etc that I was really struggling to model in myself
However, I would not recommend it as a 'standard workflow' - it is FAR faster and less effort to just draw things manually
